[Freeswitch-users] SIP codec preference order

[Muhammad Shahzad]

Hi,

I have a FS gateway (SVN revision 14537) that is is receiving SIP calls from
different source gateways and sending it to one single destination gateway.
Now each source gateway can talk in one specific codec and FS itself is not
doing any transcoding. So i enabled all possible codecs that this FS may
receive from source gateways.

The problem is that the source gateways who are talking in codec that are in
first three preferred codecs list in sip profile are working fine, while the
codecs that are at 4th or greater preference order number do not work. The
call is received and accepted by destination gateway then it gets terminated
almost immediately.

Do note that destination gateway is not FS, its some CISCO device that is
also accepting all possible codecs.

Can you guys suggest why it is happening and what are the possible
solutions, other then transcode of course.

Thank you.
